#Api

Write a function that attempts to call an API and returns a promise. The function should retry the API call a defined number of times if it fails, ensuring there are suitable delays between retries.

How would you sync a frontend application that initiates a transaction with a bank, considering that the initial API call doesn't confirm success or failure? Discuss your approach without needing to provide code.

Describe how the API request for paginated data should be structured. Include details on the parameters you would use for this implementation.
